Since I installed Win7 on my DELL Inspiron 1520 notebook, I frequently experience BSODs.

I noticed that those nearly only happen on two occasions

  • disconnecting a DUN connection (Bluetooth, UMTS USB stick, even VPN)
  • with certain file open dialogs (most of the time UPLOADING in Firefox or Chrome, strangely enough downloading with dialog works perfect)

The BSOD doesn't appear always on these actions.

BluescreenView told me that most of the time it is

  • srv2.sys+45883 or
  • srv2.sys+42982 or
  • ntoskrnl.exe+71ef2
  • ntoskrnl.exe+71f00
  • ntoskrnl.exe+ef6a2

Now I read that srv2.sys is for NETBIOS sharing, which could be triggered when opening the file open dialog. All unused NICs are deactivated.

Any ideas how to fix this?

EDIT: The same BSODs occur after installing some drivers

See this thread: srv2.sys causing BSOD in Windows 7 Ultimate x64.

There the problem was analyzed as caused by the personal firewall, which blocks local NETBIOS ports, thus causing Windows 7 system services to crash because of denial of access to the ports, and specially the Smb 2.0 Server driver srv2.sys.

I would turn all firewalls off for a time, including that of Windows. (If you're behind a router, you don't really need a firewall in any case.) If the problem disappears, then replace your firewall by another.

The above thread also recommends updating the Asus AI Suite ATK0110 utility drive. If that applies to your case, the Asus driver updates link is here.

EDIT

According to your input, this is probably a driver problem.
In any case, a driver is always the most likely cause of a BSOD.

Your case is similar to that discussed in this thread, that discusses drivers for Win7 for the Inspiron 1520. It offers the following links:

Intel graphics drivers: Intel Download Center
nVidia graphics drivers: nVidia Drivers
Media Card Reader drivers: from Dell (listed for another laptop) in Dell Search for R234107
Dell Wireless 355 Bluetooth adapter: here

I guess the ASUS drive doesn't apply here, but +1 for the NETBIOS combined with firewall hint. Will accept if it works! –  Tarnschaf Mar 21 '10 at 17:01
    
Sorry, disabled the firewall and got another srv2.sys+42982 combined with ntoskrnl.exe+71ef2 when the open file dialog opened in my browser. –  Tarnschaf Mar 21 '10 at 18:13
    
@Tarnschaf: Have you checked for viruses? This problem is not normal. –  harrymc Mar 21 '10 at 19:14
    
I use the MSE virus scanner and checked with BitDefender: Both didn't find anything suspicious! –  Tarnschaf Mar 21 '10 at 22:08
    
Might need to check your system using "sfc /scannow". See this article: sevenforums.com/tutorials/…, as well as this one: updatexp.com/scannow-sfc.html –  harrymc Mar 22 '10 at 9:35

Try updating every driver you can download from Dell. Sounds like some sort of hardware glitch (wildly guessing without knowing the STOP number).

I'm afraid DELL does not provide win7 drivers because my notebook model is not officially supported with win7. I can't use the vista drivers because they are x86, my win7 is x64. –  Tarnschaf Mar 23 '10 at 2:48
    
I know it's not the answer you're looking for, but sometimes there's really good reason a particular OS is not supported on hardware. –  Chris S Mar 23 '10 at 12:56

Have installed your firmware? Your laptop model comes with Vista drivers and those work perfectly with Windows 7. I have Windows 7 installed on the same model and it works perfectly with the Vista drivers that came with the laptop. If you don't have your drivers CD/DVD download them from this link

Well, I run the 64 bit version of Windows, I bet you decided for the x86 one? I don't think I should or can install those drivers. –  Tarnschaf Mar 21 '10 at 22:14
